In the last trading session, U.S. stocks ended lower after rising in earlier in the day. Among the top ETFs, investors saw (SPY - Free Report) lost 0.5%, (DIA - Free Report) shed 0.4% and (QQQ - Free Report) move lower by 1.2% on the day.

Two more specialized ETFs are worth noting as both saw trading volume that was far outside of normal. In fact, both these funds experienced volume levels that were more than double their average for the most recent trading session. This could make these ETFs the ones to watch out for in the days ahead to see if this trend of extra-interest continues:

(SJNK - Free Report) : Volume 4.26 Times Average

This high-yield bond ETF was in the spotlight yesterday as nearly 6 million shares moved hands compared with an average of 1.5 million shares a day. We also saw some price movement as SJNK lost nearly 0.1% last session.

The big move was largely the result of rising bond yields that has raised demand for high-yield bond ETFs. These ETFs are less sensitive to interest rate fluctuations and provide a cushion to investors against the rising interest rates environment. SJNK shed 0.5% in the past one month and has a Zacks ETF Rank #4 (Sell) with a High-risk outlook.

(IUSV - Free Report) : Volume 4.15 Times Average

This large-cap value ETF was under the microscope yesterday as more than 1.6 million shares moved hands. This compares with an average trading day of roughly 418,000 shares and came as IUSV shed about 0.1% in the trading session.

The movement can largely be blamed on bouts of volatility that led to investors’ drive to value stocks as these are less susceptible to trending markets and their dividend payments offer safety in times of market turbulence. IUSV was down 4.5% in a month’s time and has a Zacks ETF Rank #1 (Strong Buy) with a Medium risk outlook.
